Hydraulic installation should only be performed by an individual with a complete understanding of hydraulic systems and their requirements see warning below. A careful operator is the best insurance against an accident. Fill system with WATER first and check output. Check all valves, fittings, hose clamps, etc. for wear / leaks before admitting process fluid to the system. Replace hoses when worn, cracked, or if leaking.

3 BARMOUNT BRACKET Mounting Bracket Installation: The drive mounting bracket may be installed in two ways: CDSJohn Blue has 3/4 diameter ubolts (not included) available for purchase that will allow the bracket to be mounted to the side or top of a bar using the provided holes on the back or bottom sides. Four ubolt sizes are available see the parts listing in this manual for part numbers. /2 diameter bolts (not included) to attach it to a flat surface using the holes provided in either the back and bottom sides. The ubolt holes are spaced to fit 4, 6, and 7 bars, and optional adapter plates are available to mount the bracket on a 9 bar using the back surface. Mounting holes for ½ bolts Mounting bracket ¾ Ubolt holes 3

4 Component Assembly: A.) Attach the hydraulic motor (with the ports facing out) to the mounting bracket using the ½ x /2 long bolts, lock washers, and nuts. B.) Install the idler sprocket in the slot using the ½ x 3 long bolt, tube spacer, two flat washers, nut, and jam nut as shown but do not fully tighten the nuts yet. C.) Install the 8 tooth sprocket on to the motor shaft, align it with the idler sprocket, and tighten its two set screws. Idler sprocket and hardware Example NGP6055 pump Chain assembly (see note below about length) Hydraulic motor and hardware 8T Motor sprocket D.) Install the pump with the bolts and washers supplied with it. Note that there are two different bolt patterns in the top plate for small and large pumps. Adjust the position of the pump sprocket as necessary to align it with the other sprockets. Holes for NGP8055AR pump NGP6055/8055 NGP7055/9055 Use outer bolt pattern for large pumps Use inner bolt pattern for small pumps 4

5 E.) Install the chain. Note that for NGP7055 and NGP9055 pumps it will be necessary to install two more links (supplied in the kit) onto the chain. (Note that if you have an older CDSJohn Blue Pump (e.g. LM2455/4955) or a smaller size sprocket on your pump, it may be necessary to remove links from the chain.) NGP6055/8055 NGP7055/ Link Chain 57 Link Chain F.) Slide the idler sprocket over in the slot to tighten the chain, and then tighten the nut and jam nut to lock in place. Hydraulic System: To reach full pump rpm, the hydraulic system must supply at least 9.5 gpm to the manifold inlet port, and be capable of developing at least 600 psi. The maximum gpm and pressure should not exceed 0 gpm and 2750 psi. 0 gpm should not be exceeded to keep from spinning the pump above its maximum rpm. Limit the amount of flow to the pump, or use an inline bypass valve if necessary. A flow rate lower than 9.5 gpm may be used, as long as the user understands that that the piston pump cannot generate its advertised maximum flow and rpm. As supplied, the system is compatible with a closed center load sensing hydraulic system, which compensates for flow and pressure. If you have a closed center pressure compensating system, you may have to put an inline orifice before the inlet port of the manifold to make the variable stroke pump build pressure. Both of the systems above will have a tractor equipped with a flow control valve to adjust max flow. An open center hydraulic system will require the use of a flow bypass valve if the flow is too high, since this system uses a constant flow pump. Note that care must be taken to avoid overheating when bypassing a large volume of oil for long periods of time. 5

6 .) Assembly for units with the Variable Rate Manifold A.) Install the hydraulic manifold by first removing the four bolts that retain the port shipping cover plate on the hydraulic motor. B.) Ensure that the orings are in place in each port. C.) Then install the manifold by using the four 5/6 x 2 Lg. socket head cap screws. D.) Install the 90 degree elbow fittings (provided with the kit) into the inlet (bottom) and outlet (top) ports. (The fittings adapt from #8 SAE oring ports on the manifold to #8 JIC male 37degree.) E.) Have hose assemblies made (using hydraulic hose with a working pressure rated at or above your system pressure) to fit your specific installation. F.) It is recommended that a hydraulic filter be used in the inlet line for the motor. #8 JIC male long elbow outlet fitting * Use hydraulic hose with a working pressure rated at or above your system pressure Hydraulic Manifold and 5/6 SHCS Bypass valve Low backpressure return line Flow control valve (servo type shown) #8 JIC male elbow inlet fitting Tractor hydraulic pump gpm max 600 psi min / 2750 psi max Filter recommended G.) Finishing the Installation: Please refer to the specific installation manual for your control for instructions on how to connect the flow control valve and bypass valve harnesses, and how to configure the control to work with these components. 6

7 2.) Assembly for Manual Speed Control units (which do not have a manifold) A.) Connect your hydraulic hoses to the ½ female NPT ports on the motor (the lower port is the inlet). The hoses should be rated as specified in the previous section, and the hydraulic supply requirements are also the same as previously stated. B.) Install the supplied flow control valve in the inlet line. C.) It is recommended that a hydraulic filter be used in the inlet line for the motor D.) Use the supplied optical tachometer to determine the speed of the pump by placing a piece of the reflective tape on the pump sprocket. Pump output in GPM can be calculated with the following formula: GPM = RPM x (pump displacement) x (scale wheel setting)/0 Pump Series: NGP6050 NGP7050 NGP8050 NGP9050 Pump Displacement (max at 0) Gal/Rev Max Operating Speed: RPM Output Volume (max) Gal/Min Alternatively, pump output can be monitored with a flowmeter and a digital readout. An example of this setup would be MicroTrak s FM270 and FloPro control/readout. E.) Adjust the pump speed with the hydraulic flow control valve. ½ NPT outlet port * Use hydraulic hose with a working pressure rated at or above your system pressure Hydraulic motor Low backpressure return line ½ NPT inlet port Manually adjusted flow control valve Filter recommended Tractor hydraulic pump 9.5 0gpm max 600 psi min / 2750 psi max 7

9 NGP DIRECTDRIVE BRACKET Installation: The directdrive bracket can only be assembled to standard NGP pumps. Two different brackets are available for 6055/8055 series and 7055/9055 series pumps. The bracket mounts both under and to the side of the pump. All other components remain the same as what is shown on page 8, and the hydraulic connections remain the same with the exception that the manifold has been rotated 80 degrees.. Remove three 5/6 side cover bolts that will be used to attach bracket. 2. Remove and reverse sprocket on pump shaft. 3. Place bracket and pump in position, install pump foot mounting bolts (tighten loosely), and install three side cover bolts with included flat and lock washers. Use spacer bar if installing on a double pump (8055 or 9055). Tighten side cover bolts before tightening pump foot mounting bolts. Use sealant on side cover bolt threads. 4. Install motor, sprocket and chain. Position sprocket to align chain, and rotate motor to tighten. 5. See pages 5, 6, and 7 for details on how to connect to the hydraulic system. Motor, manifold, and hardware are same as on page 8 Inlet fitting Reuse three 5/6 side cover bolts with items #3 & #4. Use sealant on bolt threads. Tighten before pump mounting bolts (PWM valve shown no bypass) 2 **IMPORTANT ** Remove and reverse pump sprocket on shaft Bracket lower leg goes under pump 5 Outlet fitting Item Part Number Description Qty a Mounting bracket for NGP6055 (& 8055 USING 6300 SPACER) Mounting bracket for NGP7055 (& 9055 USING 6300 SPACER) 2 2a Chain for 6055/8055 Chain for 7055/ /6 flat washer /6 lock washer Double pump spacer bar (place under feet of pump on far side) 9
